帮忙写一个桌面日历备忘录代码

好的，以下是一个简单的桌面日历备忘录的 Python 代码，你可以在本地运行：

import tkinter as tk
import calendar
from tkinter import messagebox

class CalendarGUI:
    def __init__(self, root):
        self.root = root
        self.root.title("日历备忘录")

        self.year = tk.StringVar()
        self.month = tk.StringVar()
        self.date = tk.StringVar()
        self.event = tk.StringVar()

        self.create_widgets()

    def create_widgets(self):
        self.label_year = tk.Label(self.root, text="请输入年份：")
        self.entry_year = tk.Entry(self.root, textvariable=self.year)

        self.label_month = tk.Label(self.root, text="请输入月份：")
        self.entry_month = tk.Entry(self.root, textvariable=self.month)

        self.label_date = tk.Label(self.root, text="请输入日期：")
        self.entry_date = tk.Entry(self.root, textvariable=self.date)

        self.label_event = tk.Label(self.root, text="请输入备忘事件：")
        self.entry_event = tk.Entry(self.root, textvariable=self.event)

        self.btn_show = tk.Button(self.root, text="显示日历", command=self.show_calendar)
        self.btn_add = tk.Button(self.root, text="添加备忘", command=self.add_event)
        self.btn_quit = tk.Button(self.root, text="退出", command=self.root.quit)

        self.label_year.grid(row=0, column=0, padx=5, pady=5)
        self.entry_year.grid(row=0, column=1, padx=5, pady=5)

        self.label_month.grid(row=1, column=0, padx=5, pady=5)
        self.entry_month.grid(row=1, column=1, padx=5, pady=5)

        self.label_date.grid(row=2, column=0, padx=5, pady=5)
        self.entry_date.grid(row=2, column=1, padx=5, pady=5)

        self.label_event.grid(row=3, column=0, padx=5, pady=5)
        self.entry_event.grid(row=3, column=1, padx=5, pady=5)

        self.btn_show.grid(row=4, column=0, padx=5, pady=5)
        self.btn_add.grid(row=4, column=1, padx=5, pady=5)
        self.btn_quit.grid(row=5, column=0, columnspan=2, padx=5, pady=5)

    def show_calendar(self):
        year = int(self.year.get())
        month = int(self.month.get())

        cal = calendar.monthcalendar(year, month)

        self.calendar_window = tk.Toplevel(self.root)
        self.calendar_window.title("日历")

        for i in range(len(cal)):
            for j in range(len(cal[i])):
                if cal[i][j] == 0:
                    continue

                tk.Label(self.calendar_window, text=cal[i][j]).grid(row=i, column=j, padx=5, pady=5)

    def add_event(self):
        year = self.year.get()
        month = self.month.get()
        date = self.date.get()
        event = self.event.get()

        if not year or not month or not date or not event:
            messagebox.showerror("错误", "请输入完整信息")
            return

        with open("events.txt", "a") as f:
            f.write(f"{year}-{month}-{date} {event}\n")

        messagebox.showinfo("提示", "备忘添加成功")

root = tk.Tk()
app = CalendarGUI(root)
root.mainloop()

这个代码使用了 Tkinter 库来创建 GUI 界面和显示日历，使用了 Python 自带的 `calendar` 模块来生成日历。同时还可以添加备忘事件，将备忘事件保存到本地的 `events.txt` 文件中。你可以根据实际需求对代码进行修改和完善。
